POWER-TRANSMITTNG MECHANISM.

To all whom t may conce-m:

Be it known that we, FRANK A. KiNMoN'i nand RoBERT F. KINMONT, residin@- at Los Angeles, in the county of l Los Ange es, State of California, have invented a new and useful Improvemnt- ,in Power-Transmitting I Mechanisms.

1 This invention relates to that class of power transmission devices more especially adapted to lifting purposes and an object is to provide a mechanicalstructure that will convert rotary movement intoreciproc ating action byl means of flexible connections.

lt is also an important object -to provide a power transmitting mechanism whereby rotary action is converted into reciprocating motion with the part-s in perfect balance. It is a further object to provide a power transmitting mechanism which will accomplish the above object with the least friction in' the most efficient and economical manner. t

In the drawings accompanying this specification and forming a part of the application for Letters Patent; Figure-1 is an end elevation of our device. Fig. 2 is a longitudinal sectional elevation of the device showing the reciprocating member adapted to a lifting pump. Fig. 3 is a sect-ion on line 3-3 of the following Fig. 4. kFig. 4

is a cross section on line 4 4 of Fig. 2.1ooking in the direction of the arrows. Fig. 5 is a sectional det-ail on line 5*-5 showing the links .connected to the roller.

More specifically in the drawings, 10 represents the base on which is built the frame composed of vertical columns 11, securedl t-o the base in .any suitable manner and united at their top by a suitable cross' head 12, secured by bolts 13 to the flanged columns.` Suitably mounted on the frame and extending'across the end, projecting on- 1 either sideis shaft 14 suitably journaled in Fig. 2.

bearingsv 15 secured tothe columns adjacent to that portion of the device. One end of the shaft is shown of greater length and carried on its extended end, keyed in any suitable manner the pulley wheel 16, shown driveny by the belt' 17 from any suitable source of power. Also mounted on the shaft externally to the columns are the gears'18and 19 securely keyed `to the-shaft and rotating in unison therewith preferably in the direction shown by the arrows in specification of Letters Patent. Patented May 19, 1914', Application'led .Tune 13, 19'12. Serial No. 703,557.

Vsame axial plane and supported by the columns and crosshead. Mounted on the exterior ends of these shafts are the pinion wheels 24 and 25 meshing respectively with the pinions 18 and 19,` their internal ends carrying sprocket wheels 26 and 2'? which are adapted to engage sprocketchains and actuate the latter. `In the same horizontal plane and occupying the same relative position in relation to the structure are the c'operating shaft 28 and its mate, (hidden in the drawing), which respectively bear on their external ends gear wheels 30 and 31 which in their turn mesh respectively with the-gears 24 and 25 which are of necessity all built of the same size. Shaft 28 and its mate-also bear on their interior ends sprocket wheel 32 and mate not shown of the same number of teeth and same size as those carried on the cooperating shafts 2O and 21.

VIn the same vertical plane with the four shafts, coperating at the upper portion of the frame are placed four idler shafts 34, 35, 36 and 37 revolving in'sutable bearings secured to the respective columns adjacent to the shafts. The inner ends of these idler shafts terminate in the same relative position as their corresponding member above and carry on these ends sprocket wheels 38,

39, 40 and 41 of the same size and number of sprockets as those placed above. Traveling over these sprockets and in corresponding vert-ical planes are four sprocket chains '42, 4e, 44 and. 45.

In an axial plane mounted centrally with the ,four sprocket chains is provided a pump frod'46 journalcddli the base of the structure at' 47 and provided with a cross aim 48.

The cross arm extends in the plane from end toend of the machine andy is provided with tion of slot bei-ngprovided with removable sections 50 secured in place by the bolts 51. These guide slots register opposite the path of the adjacent pair of sprocket chains, one member of the sprocket chain with the pinion link on the opposite side supporting between them the roller52 provided with ball bearings 53 revolving around the shaft 54 which, as before stated, is supported by links -55, forming a section of thc chains.`

longitudinal guide'slots 49, the lower pordrawings they are inserted by removing the section of the slide' 50 and slipped into the cross-head'slot, the annular flanges bearing Von the external faces of the cross head and guiding the roller in the cross head. These rollers'are placed on the adjacent coperating portions of the four sprocket chains so that their action is exerted at the same relative`distance from the center of the reciprocating member. j

As will be readily seen in the operation of our device, power transmitted to the pulley `16 by any'suitable -means driving the same in the direction of the arrows, moves the gears, meshingr with them in the direction, also indicated by the arrows and revolving. the shafts in opposite direction, carries the sprocket chains over their respective sprockets in the direction of the arrows and in exactly a coperative movement and direction,- will lift the cross head to a position slightly above the axial plane of the upper side of shafts when the roller by the action of the chain will travel upward and momentarily the reciprocating action willcease until the further movement of the chainsc-arries the rollers down and assisted by gravity carries the reciprocating member downwardly.

` As the least pressure alls'upon the lower side of the slot, the removable rtionf50 has preferably been inserted in this position and the pump rod has been shown threaded into the cross head, but other suitable methods may be adopted and' tension devices could be applied to the idler shafts if found necessary.

In Fig. 3 the links 55 are shown with their pins 57 and the connecting bar or rej inforcement 58 which materially strengthens the device as shown clearly in Fig. 5.

What we claim is:

1. A power transmitting mechanism, comprising a rotating ldriving member, a reciprocating member mounted adjacent thereto, across head secured to and extending on either side of said reciprocating member registering pair of said par chains,

providedwith a pair of oppositely disposed slots, a plurality of adjacent coperating pairs of parallel sprocket chains registering with and adapted to `pass, in parallel .direction adjacent to and on both sides of said cross head and each slot, pivotally mounted on a shaft connecting a parallel moving pair of said chains and means to connect'said chains to said rotatingmember.

. 2. A power transmitting mechanism, comprising a rotating member, a reciprocating member mounted adjacent thereto, two co-n operating parallel pairs/of sprocket chains adapted to transmit motion from the rotating member tothe reciprocating member, a cross head secured to lsaid reciprocating member having oppositely disposed on either side of said member slots registering with the parallel and adjacent path of travelA of 'said parallel pairs of sprocket-chains, and means interposed between a' pair of op 0'- sitely disposed links of said pairs of para lel chains and engagijingsaid. slots, wherebyr a balanced and parallel lift is obtained. A 3. A powertransmitting mechanism, comprising a rotating driving member,a reci rocating member, a cross head transverse y disposed on said reciprocating member rovided with slots each having a recessed e ge, a sprocket chain registering on either side of said slots in said cross head) 'flanged rollers mounted in the slots and connectin a fllel sprocet sections to tsaid re esses in said slots to allow4 for the/insertion of said anged rollers, and means to'connect 'said sprocket chains to said rotating member,v whereby the adjacent legs of said chains pass in parallel relation and equal speed, to maintain a balanced lift on said reciprocating member. In witness that we claim the foregoing we have hereunto subscribed our names this 6th day of J une, 1912. l
